	<h1>Numeric filtering and master checkbox</h1>
	<p> Grid provides filtering by a numeric value. Just try to enter value in the header. Setting special parameters in footer allows to process column's numeric data.<br/>
		Sample demonstates also the master checkbox in the header. Try to select checkbox and then all cells in a column will be checked, vice versa as well.
